And then display:
displays Left and Right channel
outputs POWR(0W), displays Left and
Right channel CLIP(ON/OFF),
displays Left and Right channel
PROT(ON/OFF),displays Left and
Right channel heat sink TEMP(oC)
and displays left and right channel
output level meters, you can view the
values of the output signal and view
how many power output.
If stereo/bridge switch or limiter switch
or potentiometer action, and then you
can view this screen, you can view
stereo/bridge working mode and
limiter switch set position ,and shows
left and right channel output
attenuation histogram, and read the
value of the output attenuation,output
attenuation range from -
to 0dB. After
a few seconds return to second screen .
Press 4/8
tact switch ,you can view
this screen, after a few seconds return
to second screen.If you select 8
the
output power value is 8
,else show
output power is 4

Two front-panel mounting holes are provided on each mounting ear.
Series amplifiers are cooled by fan.Cool air flows over the heat sink and exhausts
through the front grill.Make sure this outlet remains clear to allow unrestricted airflow.
Two input attenuators adjust level for their respective amplifier channels. In Bridged Mono
modes, the channel A attenuator controls overall signal level (see rear panel mode switch
description).
This Red LED indicates that the amp channel is in Protect mode.During Power up, the amp
briefly goes into protect mode in order to prevent any loud speakers from being fed the
speakers. After a few seconds the amp comes out of protect mode and is ready for normal
operation. If the amp stays in Protect mode, this indicates that there may be a problem internal
to the amp. If the amp goes into Protect mode during operation this indicates that either a
problem has developed internal to the amp or the amp is being over-stressed and needs to
cool down. After a Protect condition, the amp must be reset by cycling the power off and then
on again in order to continue using it.
When the output power exceeds the safe working range of the amplifier,the CLIP LED are lit.
LCD display as: Company name/logo, detailed power at 2ohm/4ohm/8ohm,Limiter,Working
mode, Protection(L/R), Level(L/R), Temperature(L/R heatsink), Clip(L/R), Gain(L/R),Detail
wiring diagram you can refer to
.
SIGNAL LEDS inintensity inresponse to signals up to -30dB.-20dB to -10dB LEDS indicate
output levels.
This switch turns the amp on and off.
